. Electrical world. ttery was opened up so that the interior con-struction and the nature of the basswood and rubber separators, etc.,could be observed. The lugs on the plates are extremely substantialand heavy. The second type shown was the latest form with heavylugs for ordinary automobile work, and the third type was a verycompact little set devised for sparking purposes on gasoline and otherhydrocarbon vehicles. All of these are jn extensive use sets of Electric Storage Battery Companys cells were to befound around the exhibition, notably one in the space of the General Electric Company, being charged by means, of alternating currenttaken through a mercury arc rectifier. The General Electric Company had a most interesting and com-prehensive exhibit at the Fourth Avenue end of the hall, comprisingits new motors, controller, panelboard, etc., details of which aregiven elsewhere in this issue, and particularly its novel form ofmercury arc rectifier. Under the care of Mr. A. Churchward a set. FIG. 2.^EXHIBIT of NATIONAL ELECTRIC .\UTOMUBlLti. was shown of apparatus including a rotary reversed, taking thedirect current of the house and delivering single-phase current to themercury arc rectifier, whose operation could be witnessed throughglass. This rectifier straightened out the current and delivered itto a set of Exide cells and the quantity of current going into thebattery could be noted from the indicating instruments on the attracted a great deal of attention, especially as experimentswere made to show flexibility under a range of frequency and underother varying conditions. Mr. Churchward stated that he had beencharging storage batteries for practical work in this way for sixmonths past.
